An important component of the starting phases of the Big-Bee project is the formulation of a consistent protocol for imaging specimens with labels. As part of this protocol, we needed to determine which measurement tool would be both accessible, accurate and precise for all participants. For this reason, we performed an initial assessment of five standard rulers using a microscope reticle as a comparison.
The five measurement were from four rulers which were available for purchase online:
#Forestry Ruler which costs about $1.25
#Forensics Ruler which costs about $2
#Builders Ruler which costs about $35 (For this Ruler two measurements were taken to determine if specific calibration points, 1.5 and 3.5, yielded differences in accuracy on the same tool.
#Microscope slide ruler which costs about $14
